Abstract: 송신장치에 광파(LASER Diode 또는 적외 LED)를 조사하고 그 반사광을 수신하는 시스템에서는 갑작스런 섬광이나 배경광 등의 영향으로 치명적인 에러를 일으킨다. 이에대한 보상방법으로는 일반적으로 송신광원을 변조하거나 또는 수신장치의 센서 앞부분에 광학필터를 추가하여 보상하게 된다. 
     일반적으로 반사광을 이용한 수신장치의 광학필터를 이용한 배경 광잡음(섬광 또는 태양광) 제거방법은 광학필터 사용으로 인한 수신광량의 감소 때문에 비교적 저렴한 LED를 사용치 못하고 고가의 LASER Diode를 사용해야 하며, 광학필터 자체의 고가성 때문에 시스템 전체의 가격이 상승된다. 
     본 발명에 따르면, 광파를 이용한 수신장치에서의 단점으로 지적되는 배경 광잡음을 광학적인 방법이 아닌 전자회로적으로 제거할 수 있는 방법 및 회로가 제시된다. 또한 수신장치에 광학필터를 사용하지 않으므로 수신장치의 가격이 저렴해지며, 아울러 송신광원을 구동이 쉽고 온도영향에 민감하지 않은 적외 LED를 사용할 수 있으므로 레이저다이오드를 사용하는 송신장치에 비해 저렴하고, 구동회로가 간단하며, 신뢰성이 높은 송신장치를 구현할 수 있다.
